PROCESS FOR THE MANUFACTURE OF POLYUREA FOAMS

摘要

A process for the manufature of polyurea foams which comprises reacting an organic polyisocyanate with at least a chemically equivalent amount of water in the presence of a catalyst for the reaction and a triaryl phosphate and/or an aromatic halogen compound. The foams are more resistant to the effects of prolonged exposure to heat or humidity than similar foams containing tris(halogenoalkyl)phosphates.
